[0021] See Figure 1 、 2 Figures 3 and 4 are schematic structural diagrams of a preferred embodiment of the present invention. The present invention relates to a rotary contact connector base, comprising a ring-shaped insulating base 1 and a first ring terminal 2 and a second ring terminal 3 injection-molded together with the insulating base 1. The upper side surfaces of the first ring terminal 2 and the second ring terminal 3 are exposed from the insulating base 1, allowing the first ring terminal 2 and the second ring terminal 3 to simultaneously contact and connect with an external rotary male seat assembly 4. The integrated structure not only ensures stable assembly of the first and second ring terminals 2 and 3, preventing them from deforming or loosening, but also ensures that the upper side surfaces of the first and second ring terminals 2 and 3 are stable, facilitating stable contact and connection with the external rotary male seat assembly 4 and ensuring signal transmission. During implementation, the insulating base 1 is fixed to a corresponding carrier, exposing the upper side surfaces of the first and second ring terminals 2 and 3, allowing them to contact and connect with the external rotary male seat assembly 4, thereby constructing a stable and reliable 360-degree rotary connector that can be used to transmit power or data signals. Figure 1 、 2As shown, the rotating male seat assembly 4 is provided with two contacts 41 that can rotate forward and reverse along the rings of the first ring terminal 2 and the second ring terminal 3. The two contacts 41 respectively press against the first ring terminal 2 and the second ring terminal 3 to form a circuit for signal transmission. The insulating base 1 is provided with an isolation ring 11. The isolation ring 11 is located between the first ring terminal 2 and the second ring terminal 3 to effectively prevent short circuits. The isolation ring 11 is provided with an air gap 111, so that the inner side of the first ring terminal 2 and the outer side of the second ring terminal 3 can be exposed through the air gap 111 and face each other, adjusting the impedance characteristics between the first ring terminal 2 and the second ring terminal 3 to meet the requirements of higher speeds, achieve high frequencies, and facilitate signal transmission. In this embodiment, there are four air gaps 111 and they are evenly arranged along the trajectory of the isolation ring 11, increasing the facing area of the first ring terminal 2 and the second ring terminal 3, further improving the impedance characteristics. The air gap 111 in this embodiment is obtained by partially reducing the material of the isolation ring 11, and a through hole is provided at the bottom of the air gap 111 and extends to the bottom surface of the insulating base 1, which is conducive to air flow, improves the impedance characteristics of the first ring terminal 2 and the second ring terminal 3, and can also provide heat dissipation, thereby ensuring the performance and life of the first ring terminal 2 and the second ring terminal 3.
[0022] Figure 1 、 2As shown in Figures 3 and 3, in this embodiment, the first ring terminal 2 is provided with a first grabbing portion 21, and the first grabbing portion 21 is embedded in the insulating base 1 during injection molding; the second ring terminal 3 is provided with a second grabbing portion 31, and the second grabbing portion 31 is embedded in the insulating base 1 during injection molding. The first grabbing portion 21 and the second grabbing portion 31 are used to penetrate into the insulating base 1 to increase the mechanical connection performance and further prevent the first ring terminal 2 and the second ring terminal 3 from being deformed and loosened. The first ring terminal 2 is a stamping part, and the first grabbing portion 21 is a structure in which the outer edge of the first ring terminal 2 is partially cut and bent downward, and the first grabbing portion 21 is provided with a first hanging hole 211, and the first hanging hole 211 is used for part of the molding material of the insulating base 1 to pass through and hang. And the second ring terminal 3 is also a stamped part. The second gripping part 31 is a structure in which the residual material of the inner side of the second ring terminal 3 is partially cut and bent downward, and the second gripping part 31 is provided with a second hanging hole 311, and the second hanging hole 311 is used for hanging part of the molding material of the insulating base 1. The design of the first hanging hole 211 and the second hanging hole 311 increases the material climbing and hanging during injection molding, improves the assembly stability of the first ring terminal 2 and the second ring terminal 3, reduces problems such as deformation, cracking and burring during use, and improves the performance of use. In this embodiment, there are multiple first gripping parts 21 and second gripping parts 31, which are arranged at intervals along the main body of the first ring terminal 2 and the second ring terminal 3, respectively, to increase the connection points, ensure that the first ring terminal 2 and the second ring terminal 3 are firmly assembled and connected, and can ensure that the upper side surfaces of the first ring terminal 2 and the second ring terminal 3 are stable, which is conducive to stable contact and connection with the external rotating male seat assembly 4.
[0023] Figure 1 、 2 As shown in Figures 3 and 4, in this embodiment, preferably, the widths of the first and second ring terminals 2, 3 are consistent, forming a dual runway of inner and outer rings. The insulating base 1 is also provided with a plurality of air holes 12, each extending to the lower side surfaces of the first and second ring terminals 2, 3, so that the lower side surfaces of the first and second ring terminals 2, 3 are partially exposed through the air holes 12 for heat dissipation. The air holes 12 are opened upward from the lower bottom surface of the insulating base 1, perpendicularly facing the first and second ring terminals 2, 3. Preferably, the air holes 12 are square in shape, and the width dimension of the air holes 12 in the first and second ring terminals 2, 3 is at least half of the width dimension of the first and second ring terminals 2, 3, and the air holes 12 are centered and facing each other. At the same time, two adjacent air holes 12 corresponding to the first and second ring terminals 2, 3, are arranged side by side in the same area. This effectively ensures consistent heat dissipation of the first and second ring terminals 2, 3, and facilitates signal transmission.
[0024] In this embodiment, the isolation ring 11 is injection molded together with the insulating base 1, and the upper side surfaces of the first and second ring terminals 2 and 3 are flush with the upper end surface of the isolation ring 11, facilitating contact and connection with the external rotating male socket assembly 4 and reducing interference. The first ring terminal 2 is provided with a first solder pin 22, which extends downward from a first clearance notch 13 reserved on the outer ring edge of the insulating base 1. The second ring terminal 3 is provided with a second solder pin 32, which extends downward from a second clearance notch 14 reserved on the inner ring edge of the insulating base 1. The addition of dedicated first and second solder pins 22 and 32 ensures that soldering connections can be made within the orthographic projection area of the insulating base 1, facilitating product assembly and optimizing the overall product size.
[0025] The utility model realizes that the first ring terminal and the second ring terminal are both injection-molded together with the insulating base to form a whole with a stable and reliable structure. The first ring terminal and the second ring terminal are arranged in an inlaid manner, which is not easy to fail or deform, and can provide a stable contact plane, which is conducive to stable contact and connection with the external rotating male seat component, and constructs a 360-degree rotating connector with stable performance and reliability to ensure signal transmission.
